I have an invisioned plan to have my own SaaS for testing application easily. Before Docker came about I was working on hacking my own solution via Squashfs but didn't get anywhere and after many months of having the project become stale, Docker comes along and looks like a good solution. I eventually became busy and didn't really have a chance to work look at Docker until last Friday. I ended up finding this a article titled SaaS Memcached and this motivated me to try looking into my SaaS again.

After I downloaded the Raring kernel, I installed them via the
dpkg -i *.deb
Now it's time to install Docker
echo 'deb http://ppa.launchpad.net/dotcloud/lxc-docker/ubuntu precise main' >> \ /etc/apt/sources.list apt-get update apt-get install lxc-docker
docker run -i -t base /bin/echo hello world
